Another tip: I found upgrading the NUC's firmware helped a lot. However, |
| 21 |
be warned that Intel has been removing support for Legacy booting in |
| 22 |
newer firmware. So you might want to get yours to boot in UEFI first, |
| 23 |
then try new firmware. |

I suspect it's a hardware limitation, but you never know. |
